Definitions

  • This invention relates generally to electrical connectors for terminating multiconductor electrical cables and pertains more particularly to terminating shielded multiconductor cables and for continuing cable shielding through the connector and the connection interface.
  • Fig. 1 depicts an electrical connector jack (receptacle) which is commonly known by the standard designation "RJ45".
  • RJ45 connector jack 10 is adapted to terminate multiconductor cable 12, which has individual electrical conductors 14.
  • Reference numeral 16 identifies a so-called “stuffer member” or “dressing block", the upper undersurface of which defines conductor-retaining undulations 16a, which maintain the conductors in position for insulation displacement connection (IDC) with electrical contacts, and latching detents 16b.
  • the conductors are extended from cable 12, e.g., by removing outer insulation thereof, by peeling back inner cable shield braiding and by untwisting the insulated conductors to lay them flat in undulations 16a.
  • the conductors are trimmed from their condition shown in Fig. 2 such that they are conterminous with the leftward end of undulations 16a.
  • stuffer member 16 So loaded with the insulated conductors, stuffer member 16 is inverted and disposed as is illustrated in Fig. 3, which illustrates a further component of the connector jack, namely, housing 18.
  • Housing 18 defines connector plug-receiving passage 18a, top-open compartment 18b and latches 18c.
  • Electrical contacts 20 are supported in housing 18 and have spring portions cantilever-disposed in passage 18a and IDC portions (not shown), which are disposed at the leftward end of compartment 18b.
  • the jack connector of Figs. 1-3 is not a shielded assembly.
  • the jack connector and the connection interface i.e., when a plug connector is inserted into passage 18a, are not afforded electromagnetic interference (EMI) protection.
  • EMI electromagnetic interference
  • sheet metal member 24 has a box-like portion 24a, having interiorly-directed lip 24b, resident aside passage 24c.
  • a rearward deck 24d has latches 24e upstanding therefrom and contact leaf 24f.
  • stuffer member 22 is constituted principally by a body of electrically insulative material.
  • the body has an uncoated part 22a, defining the undulations for conductor retention, but the remnant of the body is coated with an electrically conductive substance or substances applied in successive layers.
  • housing 18 with contacts 20 therein is inserted into sheet member 24 of Fig. 4, latches 24e becoming superimposed on latches 18c.
  • stuffer member 22 of Fig. 5 is forcibly inserted onto rearward deck 24d of sheet member 24, whereupon the events above discussed for Figs. 1-3 occur, i.e., the conductors are terminated in IDC manner and the latches 18c engage latching detents 22b.
  • contact leaf 24f engages the undersurface of stuffer member 22 to provide electrically conductivity between the sheet member and the stuffer member, which function, in effect as cooperative components of a composite EMI shield.
  • Figs. 1-5 While the commercial product of Figs. 1-5 has met technological demands for an acceptable EMI-shielded RJ45 connector jack and connector, where an exteriorly shielded plug is inserted therein, the present invention looks to improve the product in several respects.
  • the present invention has as its primary objective the provision of improved EMI shields for electrical connectors.
  • a particular object of the invention is to provide an improved EMI-shielded RJ45 connector jack and connector.
  • a quite specific object of the invention is to provide enhanced electrical continuity as between cooperative components of a composite, plural part shield for an electrical connector and to derive cable strain relief from cooperative structures of a stuffer member and a sheet member in an electrical connector.
  • an electrical connector for terminating electrical conductors of a multiconductor cable
  • the electrical connector comprising an electrically insulative housing defining an passage for receipt of an electrical connector plug and an open interior compartment, a plurality of electrical contacts supported in the housing, the contacts having first portions accessible through the housing passage and second IDC portions resident in the compartment, an electrically conductive sheet member fully circumscribing a part of the housing in which the contact first portions are resident and partly circumscribing the compartment and a stuffer member closing the compartment and dressing electrical conductors into engagement with the contact second IDC portions.
  • the stuffer member has an electrically conductive part in electrical continuity with the sheet member and a stuffer part, the stuffer part being comprised of electrically insulative material, the stuffer member and the sheet member defining structures jointly operating to provide strain relief for the cable.
  • the stuffer member and the sheet member define further structures jointly operating to provide electrical continuity between the cable shield and each of the stuffer member and the sheet member.
  • the stuffer member is preferably comprised of a body of electrically insulative material having an uncoated portion defining a stuffer part and a portion coated with an electrically conductive material, the coated portion defining wing members in interference fit with the interior of the sheet member, the stuffer member and the sheet member jointly defining an electrical shield for the electrical connector.
  • Figs. 1-3 are perspective views explaining the structure of the RJ45 electrical connector jack.
  • FIGs. 4 and 5 are perspective views depicting cooperative components of a composite shield for the above-discussed commercial product of the assignee hereof.
  • Fig. 6 is a perspective view of a sheet metal shielding member in accordance with the invention.
  • Fig. 7 is a perspective view of a stuffer member shield in accordance with the invention.
  • Fig. 8 is a plan view of the sheet metal shielding member of Fig. 6, with a latching IDC conductor terminating member inserted therein.
  • Fig. 9 is rear view of the stuffer member shield of Fig. 7.
  • Fig. 10 is a rear view of a connector in accordance with the invention shown in conjunction with a multiconductor cable, partly sectioned at plane X-X of Figs. 6 and 7.
  • sheet metal member 26 has a box-like portion 26a, having interiorly-directed lip 26b, resident aside passage 26c. A counterpart interiorly-directed lip (not shown) exists on the opposite side of passage 26c.
  • Member 26 further defines a rearward extension 26d, which has a top-open compartment 26e, which vertically full sidewalls 26f and 26g and a rear wall 26h which is vertically full except for opening 26h-1 which is in upper part rectangular and in lower, continuing part, semicircular.
  • stuffer member 28 is constituted principally by a body of electrically insulative material.
  • the body has an uncoated part 28a, defining the undulations for conductor retention, but the remnant of the body is coated with an electrically conductive substance or substances applied in successive layers.
  • the body includes a rearward, generally solid portion 28b, which supports latch member 28b-1 leftwardly thereon, and a counterpart latch member 28b-2 (Fig. 9) rightwardly thereon.
  • Forward sidewalls 28c and 28d depend from top cover 28e, which supports puller member 28f, which is useful in disassembly, given the interference fit of components discussed below.
  • Stuffer member 28 further defines a cylindrical passage 28b-3 through otherwise solid portion 28b, as is seen in Fig. 9.
  • Dimension D3 is made essentially equal to dimension D4, such that outer side extents of the stuffer member and the sheet member are flush with one another.
  • the radii of the semicircular bottom portion of passage 26h-1 and of passage 28b-3 are selected to be equal to the nominal radius of cable 12.
  • passage 28b-3 is so positioned vertically of body portion 28b that, on stuffer member insertion, a scissor-type action occurs as between the semicircular bottom portion of passage 26h-1 and the upper semicircular portion of passage 28b-3.
  • Fig. 10 wherein the ultimate result is that the respective semicircular portions form a generally elliptical passage with the minor axis of the ellipse being less than the nominal diameter of cable 12, thereby applying strain relief to the cable.
  • the interference fit as between stuffer member sidewall 28d and sheet member sidewall 26g.
  • sidewall 26f of the sheet member has substantially coextensive surface registration with metal coated surfaces of the stuffer member, i.e., latching member 28b-1 and sidewall 28c.
  • latching member 28b-1 and sidewall 28c metal coated surfaces of the stuffer member
